The level of alcohol in the body is measured by blood alcohol concentration. Average blood alcohol concentration for one ounce of alcohol is about 0.015. The permissible legal level of alcohol is around 0.08 mg/dl. At this level of alcohol concentration in the body, you can safely drive home.
10% of the alcohol is excretedby breath, perspiration, and urine. 90% of it is metabolized by the liver. The metabolism of alcohol depends on various factors like age, gender, the type of alcohol consumed, the quantity of food that was eaten, and the strength of the alcohol.
There are various measures by which alcohol concentration is measured.
